For those of you who wants to modify your FANs by adding LED lights, here's a DIY..

a simple modification..

Things needed:

• 12v DC FAN - any brands will do
• 4pcs 3v Bright LED - any color you want
• Battery operated Hand Drill - any Power Drill you have can be used
• Drill bit 3/16
• 4pin Molex (any connector you wish to use [3-pin connector])
• Super Glue - mighty bond or similar
• Soldering Iron and Lead
• Connecting Wires
• Tester - to be sure that you have the LED's + and - leg correct
• DC Power source - for testing

1st step:

• Drill a hole at each corner in whichever points you want using the drill bit 3/16.
  (can be slanted pointing @ the fan blades or pointing @ the fan motor)
  But for me, i'd rather point it @ the fan motor since my fan's not transparent

2nd step:

• Measure the wires you need, don't solder very long wires.
• Connect all four LEDs in series, by soldering the wires.
• Then solder it through the Molex or connector you've used.
• Red for +12v and Black for Ground @ the FAN
• LED's "+" point is the longer leg.
• Cut the excess wires and/or leg of the LED to make it look neat and clean
• Arrange the wires neatly - para professional pud tan.awon and you won't see a piece of junk

Theory: Voltage drop accross series connection will add, so, since we're using 3v LEDs, we need to connect it in series




3rd Step:

• Use a Super Glue to stick the LEDs @ drilled holes you've done.
• Make sure the LED won't be in the way of the FAN Blades.

(That's why I've used 3/16 drill bit so that the LED won't go any further through the hole but you can use larger than 3/16 drill bit)




4th Step:

• Test your FAN using the DC Power Source.
• if you don't have any DC Power source, make sure you've connected all necessary connections properly.

Now you can mount your FAN back to your case and appreciate your work..

FAQ - Frequently Asked Questions

Where to buy LEDs?
Any electronic shops will do but for me,
I'll go to Teknica located at Echavez st. for 12.50 pesos each.
Make sure you'll say BRIGHT LED.
coz there are LEDs that have dimmer light.

What if I don't know how to solder?
Find a technician who can do those soldering for you
(WARNING!!! Soldering Lead are harmful if you inhaled the smoke)

What if I don't have a Hand Drill?
I don't know where to find who can do that job for you.
But you can buy cheap Hand drills @ some electronic or hardware stores.
Just ask if there's a drill bit 3/16 or bigger.

What if I don't have a DC Power Source?
You're PSU is a DC Power source.
You can use your PC for testing but @ your own risk,
especially if you have connected the wires all wrong, might damage your PSU or MOBO if you have the + and - mixed up.
But just make sure the DC fan is @ Red Wire for +12v and Black for ground from the FAN wirings.
Soldered @ +12v Yellow of the Molex from the PSU.
For the LEDs, if you've got the connections wrong, it won't light and might get busted.
You'll need to buy new ones..

Why do this DIY FAN Led?
I have nothing to do on Sundays, Tuesdays and Thursdays coz I have no class on those days.

===================

• You can go creative on those modifications and it's up to you on how you'll design your LED lights.
  like this http://www.overclockers.com/articles775/
• You can add LEDs but as long as it'll total to 12v and connect the additional LED with a parallel connection from the source (more than 4 LEDs).
• Lesser than 12v total of LEDs, you'll be needing 100 - 200 OHMS resistor, depending on the total voltage. (just ask any engineering/technician if you don't know)
• Do this @ your own risk! I'm not liable to any damage to your system/FAN.
  I'm just sharing what i've done and did this DIY without any damage to my system and other components.

Positive and Negative feedbacks are welcome here.
pero ayaw pud mo pangaway.. hehehe..

electrician ka bro or modder?

THANKS for the info bro...much appreciated! :mrgreen:

musta naman ka bro?

[darkdevil]

But just make sure the DC fan is @ Red Wire for +12v and Black for ground.

yellow man cguro bai for +12v

naa sad lain ai...

nice info... thanks for idea...

@emoners, computer engineering ko bro.. still the same here. wa ko'y money for upgrades pa.. hehehe..

Wa ko'y buhaton man gud Tuesday, thursdays and sundays.. Medyo na bored na pud akong life, mao naghimo ko'g ingani.. hehe..

@darkdevil, Yellow ang sa PSU for +12v, Ang RED na +12v ako pasabot kay sa fan coz i-solda man ni siya sa molex or 3-pin connector... i-clarify lang nako.. I'll just edit the first post aron matarong kung unsa ako pasabot sa +12v nga wire.. thanks for the reminder..

@stealthghost...

hehehe..wa lang diay ko ka gets sa imo pasabot...
pasensya bai...

bro wouldn't leds consume more power? & which led uses less power? di ba red uses less power compared to blue? correct me if i'm wrong ha

Advantages of using LEDs

* LEDs produce more light per watt than do incandescent bulbs; this is useful in battery powered or energy-saving devices.
* LEDs can emit light of an intended color without the use of color filters that traditional lighting methods require. This is more efficient and can lower initial costs.
* The solid package of an LED can be designed to focus its light. Incandescent and fluorescent sources often require an external reflector to collect light and direct it in a usable manner.
* When used in applications where dimming is required, LEDs do not change their color tint as the current passing through them is lowered, unlike incandescent lamps, which turn yellow.
* LEDs are ideal for use in applications that are subject to frequent on-off cycling, unlike fluorescent lamps that burn out more quickly when cycled frequently, or HID lamps that require a long time before restarting.
* LEDs, being solid state components, are difficult to damage with external shock. Fluorescent and incandescent bulbs are easily broken if dropped on the ground.
* LEDs have an extremely long life span. One manufacturer has calculated the ETTF (Estimated Time To Failure) for their LEDs to be between 100,000 and 1,000,000 hours.[20] Fluorescent tubes typically are rated at about 30,000 hours, and incandescent light bulbs at 1,000-2,000 hours.
* LEDs mostly fail by dimming over time, rather than the abrupt burn-out of incandescent bulbs.[21]
* LEDs light up very quickly. A typical red indicator LED will achieve full brightness in microseconds; LEDs used in communications devices can have even faster response times.
* LEDs can be very small and are easily populated onto printed circuit boards.
* LEDs do not contain mercury, while compact fluorescent lamps do.

nice DIY tip stealthghost ... :mrgreen:

@emoners,

Most typical LEDs are designed to operate with no more than 30–60 milliwatts of electrical power.
